Rogue Engineering has spent years in research
and development, trying to make this system like no other on the
market. This Rogue Engineering E39 M5 Exhaust is unique from the
bottom up. The design, sound, and horsepower gains are far
superior to any other system for the E39 M5. Be the first to rock
one of this Rogue Engineering exhaust systems.

One sound does not fit all.

The
Rogue Engineering E39 M5 Diablo is more than just great sounding
exhaust. By studying the factory exhaust system, it just made
sense to develop the exhaust the way we did.

After
studying the benefits of a muffler-only replacement, we worked on the
sound. We wanted a deep, rich sound, without it too much
volume. Like all of our exhaust products, sound is controlled
with internal muffler tuning done the old fashioned way, tweaking the
dimensions of the muffler, as well as the internal perforated tubing
(perforation size, spacing, and tubing length). The result is a
rich, deep tone, that does NOT intrude into the cabin.

For
those looking for slightly more sound, also without drone, we also
offer our Rogue Engineering E39 M5 X-pipe, which can be used with our
E39 M5 Diablo exhaust. The resonated x-pipe removes the
restrictive factory resonator, without introducing ear-numbing drone.

E39 M5 Diablo Features
The RE E39 M5 Diablo is made to fit exactly like factory.
Features include:

Weighs only 21 lbs. per
side. When used with the optional RE E39 M5 X-Pipe (sold
separately), total weight is only 60 lbs. (stock is 98 lbs.), saving 38
lbs. over stock.

100% T-304 stainless steel
construction and internals, a majority of the exhaust made from 16
gauge stainless steel.

All Stainless Steel is the same, right? WRONG!All Rogue Engineering
Diablo exhaust are produced using only 100% full T-304 stainless steel
because of its consistent strength characteristics, corrosion
resistance, and wide range of materials (important for controlling
sound and exhaust flow). Recently, we examined a well known
exhaust brand only to discover the use of 20 gauge stainless steel
(stainless is typically sold by weight) throughout the muffler
body. While great for reducing weight, this is not a good
practice when trying to build a product to last. This common
practice of weight (and cost) savings occurs in European and US made
exhausts. Rogue Engineering does not prescribe to this practice
in their production exhausts! We want you to enjoy the exhausts
for many years to come, even if it means sacrificing some weight
savings (all Rogue Engineering exhausts are lighter than stock units).

Beware of some companies that
pre-coat their exhaust products with "thermal coatings". In fact,
they may be hiding inferior stainless steel or inferior welding
processes. Rogue Engineering Diablo exhausts are always TIG
welded and never coated.

Some companies have chosen to
build their "stainless steel" exhausts with Grade 409 stainless,
because it is less expensive than 304. While Grade 409 will
resist atmospheric and exhaust gas corrosion, a light surface rust will
form is most all atmospheres.

Geez, What too you so long? Although production
stopped in 2003, we realized that even today, the E39 M5 represented a
large, enthusiastic group. Most other companies may have written
off older BMW models such as this, but we continue to embrace (and own)
these vehicles. Therefore, I made sense to apply our knowledge
and experience into a product we could call our own.

A cursory glance at the exhaust
easily shows how this exhaust excels in both performance while saving
weight. However, a closer look will show the pure artistry of its
construction and elements of unique design.

The heavy factory
resonator (21 lbs. by itself) primary job is to muffle sound and
eliminate exhaust "drone". It does such a great job, much of the
exhaust sound is killed by this resonator by itself. The factory
mufflers do a fantastic job of completely muffling sound in the E39
M5. So well that the only way you can really hear the vehicle is
to completely roll down all the windows to really hear the V8 exhaust
sound. Between the factory resonator and the two rear mufflers,
these components weigh a staggering 98 lbs.

In a desperate
attempt to get sound, some have tried extreme things such as complete
cutting the rear mufflers off completely and running straight
pipes. While easy to do and inexpensive at the local Midas or
Meineke muffler shop, people quickly discover that the raw, brute sound
of the V8 is intoxicating, just like a muscle-car. The grins
produced by this kind of exhaust modification quickly turn to frowns
when you try to listen to music, try to answer a business call in the
car, or simply when trying to speak to someone in the vehicle.

Some may try a more
elegant method of DIY modification and purchase aftermarket muffler/tip
combos and have the same local Midas/Meineke shop install them in place
of the factory mufflers. While a better alternative to straight
pipes, most shops will typically MIG weld, without stainless
steel. After a few months, few hundred dollars spend on generic
mufflers and mild steel MIG welding do not quite look like they belong
on a vehicle that used to have a sticker price of $72,000.
